Detailed Description

Defines the atomic element of the closure phase data class. This contains the closure phase with various additional accoutrements. This will be passed to all objects that require a closure phase data value (e.g., likelihoods) and therefore can accrete additional elements but cannot rearrange elements internally to ensure backwards compatability. Because data must never change during analysis, all elements are necessarily consts, requiring some minor gymnastics at initialization. Note that here we define the closure phase to be \({\rm arg}(V_{12} V_{23} V_{31})\).

Warning
Currently forces u1+u2+u3=0 and v1+v2+v3=0.
Todo:
Define a standard for identifying stations and sources.
